LIGHTING-FIXTURE lLeidens.

Application led October 20, 1916.

ot' Somerset, State of New Jersey, have in- Ivented certain neuf and useful Improvements in Lightinglixtures, of which the following is a specification.

The improvements relate primarily to lighting ixtures, and particularly fixtures Specification of Letters Patent.

designed to effectuate what is known as the indirect'lighting system, although they may be used for illumination of other character. They are designed to accomplish various objects, and among them the improvement of the details of construction of the fixture in the matters of strength, lightness and easy assemblage of the parts; to give the fixture an attractive `appearance, and. to aliord opportunities for variations in size and design; and to make some of the parts adn justa ble and easily detachable to meet various conditions.

" The improvements are illustrated 'in the accompanying drawings, in which Figure 1 is avertical medial section ofc. lighting fixture embodying the improvements; lFig. 2 is a plan of the same detached' with the electric wire conduit in horizontal section on the line 2--2 of Fig. 1; Fig. 3 is a ,horizontal Vsection on the line 3-3 of Fig. 1'

looking inthe direction indiccted by the crrows.

The tube A is supported from the floor beams `or other part of the building frame and provides e conduit for the insulated Wires supplying current to the incandescent lamp B and extending tliroughthe exteriagainst the ceiling. K. It has annulerflange or rim H,

orlyV threaded tube C and the usualV lttmp socket D. The pipe A supports the fixture rthrough the connecting collar or hickey E, 'which is interiorly threaded and 4reof. the pipe A and upper end of the pipe C. The spider .F.has a central threaded collar G .threaded on the Dine C. bv means of whirh g y it mayV be adiusted andv mede to fit snu a dependmg nemental' form, forming the top ringo the fixture, and this ring Hghas an upturned in# neiedge I toreceive the springcatchas' J he reflector L consists prerftbly :of apiece of sheet metal, of inverted truncated preferbly Aof or Pu tentedTebfl, 1917.

Serial No. 1536,6UE1I cone form, With ai exterior coating M of reflective material applied thereto in a plestic or fluent state si that a part of the said material passes thr )ughthe perforations L and -forms u. secure and intimate union.'

The plate L has an upturned central eo-llar N provided with vertical groovesor re-` cesses N', preferally located at diametrically opposite points, and perforetions N2 therein. The prima objects and purposes of this collar are to su r'round the socket D and to receive the uppe out-turned ends O of the spring Wire loop O, by which the bowl- 'shaped shade or-glcbe P is supported. The said shade is clal'npi d at its central aperture between the cupsheped disks R and T, the former being secured lto the lower ends of the wire loop O, by means of the screw-bolt U passing through the said disks centrally and having an ori amental nut V on its lower extremity.

In this manner u fixture of strong, com

pact and attractive rharacter is made, which f may be varied in size and external iippeetr ance as desired, unl may be quickly and easily assembled and placed in position for use. The last mentoned advantage Iis one of .considerable importance. Fixtures of this character have frequently to be placed on high ceilings, a1 d the usual and most convenient. procedura i to have the worlc man by Whom it ist ce .installed use a. step ladder. This make: it necessary for him to do the work of pacing the parts in position above his head et the top of a more or less insecure sup iort, and as the parts of these fixtures fre uently have considerable bulk and weigl t the work 'is difficult .and somewhat danger ous and involves loss of time and occasional iijury or destruction to pcrtsof the fixture. With the present im?y provements it is only necessary to screw the collar Gr of the sp1( er in place and then press the reflector up inside the ring H until `the spring-catches en; fage the upturned edger 1,' then pass the ends of the loop VO into thegrooves N' until whey engage the perforations N2. This is ione by slightly compressing the Wires, passing them into the groove and allowing them to expand when they have reached tl `e desired height. If y the' globe has not-been secured to4 the wire O- it may now be sec tred by placing `it on the cup T` and raising the. said cup to its position beneath'the p art R so thatthe bolt extends therethrough and then securing the nut V. The height of .the-globeinay be adjusted to `meetvarious colnitions, as the height of the ceiling and the a gle at which the light is to be diffused, b, means of the perforations N2 at different levels. It will be understood also that the socket is placed in position before the reflector MI isl hung and that the bulb B may be placed in position or removed at any time thereafter. The fact that' the reflector is placed in position after the spiderhas been secured-, and thesocket adjusted and connected before the reflector is placed in position gives the workman an -open space in which to make the necessary electric connections,

A quick assemblage and the ease with whichV the parts may be disconnected is a-n other great advantage, Since'it enables the manufacturer to make up reflector-s, bowls, and other parts in various sizes, colors and shapes, and assemble them in. a manner calculated to produce the desired effect or to replace them if a different effect is desired.

Various details of construction may be employed, and the parts herein described and shown replaced by other parts Without.

:departing from the spirit and scope of the invention. It will also be understood that the particular location ofthe fixture is not essential, and that it may be arranged at any point inthe room Where it can be used to advantage.
